Full-gluing dynamic balancing gyro motor

Abstract

The invention provides a full-gluing dynamic balancing gyro motor. A motor stator shaft is disposed in an end cover in a supporting manner through a high-speed bearing, and a motor stator assembly is in interference fit with the motor stator shaft. A rotor cage is in interference fit with a motor rotor, and then is disposed on the motor stator assembly and rotates along with the motor stator assembly. A cooperation part of an inner ring of the high-speed bearing with the motor stator shaft is in clearance fit, and anti-creep glue is painted between the inner ring of the high-speed bearing and the motor stator shaft. A cooperation part of an outer ring of the high-speed bearing with the end cover is also in clearance fit, and anti-creep glue is also painted between the outer ring of the high-speed bearing and the end cover. Anti-creep glue is also painted at cooperation parts of two side end parts of the rotor cage with the motor rotor. Anti-creep glue is also painted at a cooperation part of a wheel edge of the motor rotor with a shaft neck head of the end cover. An inner end face of the high-speed bearing is provided with a bearing self-correcting device. The motor employs a mode of full-glue solidifying connection to replace a mode of thread connection, changes a repeated disassembly and assembly mode that the whole gyro motor needs to be installed first and then a dynamic balancing machine is installed for balancing, and enables the dynamic balancing precision, reliability, qualified rate and production to be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of inertial components, and in particular relates to a fully glued dynamic balance gyro motor. Background technique [0002] The gyro motor belongs to the external electronic rotor type three-phase asynchronous motor. It is the core component of the electromechanical gyroscope. It provides angular momentum for the gyroscope and supports the fixed axis and precession of the gyroscope. Traditional gyro motors use threads or screws to connect the end cover and electronic rotor assembly. When the gyro motor is assembled and cannot be balanced to the required accuracy by the dynamic balancing machine, it must be repeatedly disassembled and re-selected. Replace bearings, motor rotors, stators, end covers and other parts and reassemble them. The assembly efficiency is low, and the screws are easy to loosen under vibration and impact conditions, which will increase the dynamic balance of the gyro motor, increase the...

Problems solved by technology

Traditional gyro motors use threads or screws to connect the end cover and electronic rotor assembly. When the gyro motor is assembled and cannot be balanced to the required accuracy by the dynamic balancing machine, it must be repeatedly disassembled and re-selected. Replace bearings, motor rotors, stators, end covers and other parts and reassemble them. The assembly efficiency is low, and the screws are easy to loosen under vibration and impact conditions, which will increase the dynamic balance of the gyro motor, increase the gyro drift or oscillate, and cannot To achieve precision guidance and navigation purposes, it is necessary to propose improvements
